Being ignored

Blue
This man I'm crazy about never texts or calls me. I have to text him first. Always. Sometimes he responds. Sometimes he doesn't. When I see him in person, his face lights up when he sees me and he loves my company, flirts, and tells me whenever I'm free he will make time for me. But I tried texting him multiple times and no response. Wtf? 
Years ago we had a "thing" he would always text and call me first & he wanted an actual relationship, but I ended up going for another guy, bad choice. I know I broke his heart. I've apologized and I thought we had moved on from it and I want to try again, but he won't freaking text me lol. 💔  
Any ideas of what I should do or a story of your own about being ignored?
